[Surgical treatment of recurrent renovascular hypertension].

The article analyzes the results of surgery for a recurrence of vasorenal hypertension developing as a result of an impaired major blood flow in the operated on renal artery. The main causes of the blood flow impairment in the immediate postoperational period included an expansion of indications for the primary reconstructive operation or technical drawbacks during the operation itself whilst in the long-term post-operational period the progression of the underlying disease was the principal culprit. Repeated operations on the renal arteries were performed in 19 patients, and in 28 patients surgery consisted of secondary nephrectomy. Good and satisfactory results after repeated reconstructive operations on the renal arteries were obtained in 73.3% of the cases. The operation of choice in repeated interventions is the autovenous prosthesis of the renal artery.
